In the dimly lit office gym, a curvy coworker climbs onto the treadmill, her generous ass stretching the fabric of her tight leggings. She begins a steady pace, her ample flesh jiggling with each step. The scene is innocent enough, but the way she catches her reflection in the mirror, biting her lip, suggests a hidden desire. Her body glistens with a light sheen of sweat, her breath hitching as she pushes herself harder, her ass cheeks clenching and releasing with each stride.
